Description

[Detailed Description of the Invention] The present invention relates to a utility pole tightening device for equipment mounting brackets used for mounting equipment such as controllers on poles.

The drawing shows an embodiment of the apparatus for tightening equipment mounting brackets on utility poles according to the present invention.
The device B is attached to the support fittings 1 and 2 by bending metal plates into a substantially trapezoidal shape. The center piece on the base side is made into an arc shape to fit the utility pole A, and both ends of the center piece 5 and the side pieces 1
A curved tightening receiving edge 8 is formed between 0 and 10 so that the reinforcing receiving piece 6 can be rotatably locked, and the side piece 1
In the center of 0 and 10, there is a window hole 7 for inserting the reinforcing receiving piece.
7 and communicate with this to form a T-shape and provide elongated holes 9, 9 extending over the tightening receiving edge 8, and the side pieces 10, 10 are attached to the tip sides of the side pieces 10, 10 of the support fitting 1. A receiving piece 11 is provided for connecting and further latching the above-mentioned latching fitting 4, and side pieces 10 of the lower supporting fitting 2 are provided.
The band body 3 has a cylindrical mounting bracket 12 connected to the side pieces 10, 10 at the tips of the main body pieces 3a, 3a, which are connected to each other via a connection locking piece 3b. A tightening receiving edge 13 is provided, and a horizontally long elongated hole 14 is provided on the circumferential side of the tightening receiving edge 13 in correspondence with the elongated hole 9 provided in the support fittings 1 and 2.
A cylindrical reinforcing tube 15 is engaged with the tightening receiving edge 13 provided with the elongated hole 14, and the elongated hole 1 is fitted into the reinforcing tube 15.
The bolt rods 16 are inserted from the outside of the band body 3, and the bolt rods 16 are attached to both ends of the band body 3 with their tips protruding from the elongated holes 14.

Thus, the supporting metal fitting 1 is fitted to the tips of the bolt rods 16 attached to both ends of the band body 3, and a reinforcing piece 6 having a hollow cylindrical shape that fits the tightening receiving edge 13 is engaged with the inner side of the reinforcing receiving piece 6. The nut material 17 is attached, the band body 3 is wound around the utility pole A, and the nut material 17 screwed onto one bolt rod 16 is inserted together with the tightening reinforcing piece 6 through the window hole 7 of the support fittings 1 and 2. After placing the support fittings 1 and 2 inside the tightening receiving edges 8, the nut material 17 and the like placed on the other bolt rod 16 are placed in the same manner as described above, and then both bolt rods 1
6 and 16, the upper and lower support fittings 1 and 2 are tightened to the utility pole A.

The example has a bolt 18 protruding from device B.
through the through hole 19 of the mounting bracket 12, and
The lower support fitting 2 is attached to the equipment B by screwing and tightening the nut 20 to the tip of the bolt 18 that protrudes more, and on the other hand, the upper support fitting 1 is tightened to the telephone pole A in the above manner to receive it. Equipment B on piece 11
After hanging the latching fitting 4 attached to the pole, place the lower support fitting 2 on the pole A side, and tighten the supporting fitting 2 using the band body 3 in the above-mentioned manner to complete the installation of equipment A on the pole. be.

Note that 21 in the figure shows a locking piece that locks onto the receiving piece 11 of the support metal fitting 1, and 22 represents a detachment prevention piece that locks on the lower side of the receiving piece 11.

In this case, the connection relationship between the tightening receiving edges at both ends of the band body, the tightening receiving edges of the support metal fittings, and the bolt rods can be rotated in the horizontal direction, so that the tightening work can be adjusted appropriately depending on the diameter of the utility pole. This can be done easily and reliably, and the tip of the bolt rod does not protrude outward after tightening, making it safe.

Further, since there is no large reduction in cross section near both ends of the base side of the support metal fitting, it is strong against external forces in the horizontal direction.
